Summary: This study investigates the impact of crude oil shocks on African stock markets using a Structural Vector Autoregressive model and a two-state regime smooth transition regression framework. The findings suggest that global demand shock is not significant for oil-importing countries, and there is little evidence that oil supply shock affects real stock return. The study also finds that oil-specific shock has a significant impact on most countries investigated.

Summary: This study examines the impact of Brexit, the launch of the European Green Deal, and the COVID-19 pandemic on the connectedness among carbon, stock, and renewable energy markets. The results indicate that the renewable energy market initially experiences a positive shock from the carbon market, which gradually decreases over time. The long-term connectivity between the carbon market and the stock market, and between the carbon market and the renewable energy market is close to zero. In the short term, COVID-19 strengthens the positive connectivity between the stock market and the carbon market, as well as between the renewable energy market and the carbon market. Furthermore, the negative impact of the carbon market on the renewable energy market is greater during COVID-19 compared to the release of the European Green Deal, while Brexit allows for a positive carbon price spillover to renewable energy prices.

Summary: This research specifies the difference in herding across China's conventional and new energy stock markets and finds that herding is stronger for new energy stocks. The study also reveals that during the COVID-19 pandemic, new energy stock investors tend to follow market consensus, while conventional energy stock investors are not influenced. Furthermore, information arrivals from the new energy market help weaken herding in the conventional energy market, highlighting the importance of information dissemination.

Summary: This study explores the potential of cross-sectional uncertainty (CSU) in predicting stock market volatility. Empirical findings demonstrate that a newly developed variance-based index, conditioned on economic policy uncertainty, has stronger predictive power compared to the widely used economic policy uncertainty index. Sparse methods that consider multiple predictors perform well in this context. Further research shows that the CSU index contains valuable information and delivers better predictive performance and economic value, especially during financial crises. This study extends the application of the CSU index and provides novel evidence for volatility prediction.

Summary: This paper examines the role of gold as a hedge and safe haven in European stock and sovereign bond markets. The analysis, based on evidence spanning from the Euro's inception to the COVID-19 pandemic, reveals that gold acts as a hedge for stocks, particularly after the Lehman Brothers collapse. It also demonstrates strong safe haven properties for extreme negative returns and specific events like the Lehman Brothers collapse, Greek bailout, and Brexit Referendum. However, the results do not confirm gold's safe haven property during the COVID-19 outbreak. For bonds, gold is characterized as a weak hedge and safe haven. These findings have important implications for portfolio allocation in European markets, especially for fund and risk managers.

Summary: This study investigates the impact of energy productivity gains on carbon dioxide emissions in the Next 11 countries amidst their deteriorating environmental conditions. The findings show that energy productivity improvement and financial inclusion jointly reduce CO2 emissions, but a more inclusive financial system tends to amplify emissions. Furthermore, economic growth, international trade, and urbanization increase CO2 emissions, while greater renewable energy use curbs emissions. Heterogeneous outcomes are observed among these countries, with energy productivity improvement curbing emissions in eight nations and both energy productivity and financial inclusion mitigating and boosting emissions in 55% and 18% of the Next 11 countries, respectively.

Summary: The chase for economic growth has led to global environmental degradation, posing a threat to the socioeconomic aspects of human lives. Singapore, as a global economic player, has transformed its rural setup into an urban structure to achieve higher economic growth, but this has adversely affected its environmental quality. This study analyzes the relationship between Singapore's economic activities and environmental quality, and reveals that population and economic growth are the main contributors to carbon emissions, while carbon intensity helps reduce the environmental impact. Energy intensity and structure have mixed effects on carbon emissions. The analysis also shows that Singapore has experienced strong decoupling in most study years. Expensive negative decoupling, weak decoupling, and strong negative decoupling were also observed during the study period. An expanded decomposition analysis reveals that population and economic growth deteriorate environmental quality in Singapore, while carbon intensity plays a critical role in strengthening the decoupling progress, and energy intensity and structure have a mixed effect on the decoupling process.

Summary: This study investigates the relationship between economic growth and ecological footprint for 16 European countries from 1990 to 2020. The empirical analysis reveals some correlations, including a negative correlation between foreign direct investment and ecological footprint, and an inverted U-shaped curve between GDP and ecological footprint, supporting the environmental Kuznets Curve hypothesis. Furthermore, renewable energy is found to have a negative correlation with ecological footprint, while energy structure has a positive correlation.

Summary: This paper proposes a grey box model for fuel consumption prediction of wing-diesel hybrid vessels based on feature construction. By using both parallel and series grey box modeling methods and six machine learning algorithms, twelve combinations of prediction models are established. A feature construction method based on the aerodynamic performance of the wing and the energy relationship of the hybrid system is introduced. The best combination is obtained by considering the root mean square error, and it shows improved accuracy compared to the white box model. The proposed grey box model can accurately predict the daily fuel consumption of wing-diesel hybrid vessels, contributing to operational optimization and the greenization and decarbonization of the shipping industry.

Summary: Demand-side management is crucial to smart energy systems. This paper proposes a data-driven approach to understand the relationship between energy consumption patterns and household characteristics for better DSM services. The proposed method uses a clustering algorithm to generate optimal customer groups for DSM and a deep learning model for training. The model can predict the possibility of DSM membership for a given household. The results demonstrate the usefulness of weekly energy consumption data and household socio-demographic information for distinguishing consumer groups and the potential for targeted DSM strategies.
